Description
V
This invention relates generally to electrical connectors and, more particularly, to electrical connectors of the type having a housing adapted to removably mount an electrical contact i`or mating with a complimentary contact Such electrical connectors generally include one or more passageways into which contacts are inserted and thereafter removably retained by a variety of locking elements In recent years, a great variety of low cost electri-cal connectors have been developed, particularly for use in home appliances, wherein one-piece molded housings are employed to mount one or more electrical contacts. The connectors must be field serviceable, and, therefore, the housings generally include means for releasably locking the contacts in place after termination to an appropriate conductor. Flexible latching means are conventionally utilized to engage a rear portion of the electrical contact after it is fully inserted into the housing.
One significant problem encountered with such prior art connectors is that the latching means are relatively thin and weak in order that they may provide the necessary flexure required during insertion of the electrical contact into the passageway. Thus, a rearward "pull-out" force applied to a retained contact has the tendency to bend or break the latch-ing means resulting in an undesirable or inadvertent removal of the electrical contact from the housing. Examples of typical prior art connectors relying exclusively upon thin flexible stop means are disclosed in U S. Patent Nos.
3,971,613 and 4,013,331 Another difficulty encountered in the prior art connectors results from the configuration of the electrical contacts mounted therein These contacts typically include a forward engagement section and a rearward termination section :' ~
~1~6~60 retaining a conductor in a crimp termination, This crimp termination bulges above the surface of the engagement section thereby interfering with the operation of the conneetor latch-ing means and impairing the reliability of the contact reten-tion within the connector housing, Finally, prior art connector housings of the present type o~ten have complex internal configurations which require side coring in molding, Side coring increases both tooling costs and material waste making such connectors unduly expensive and therefore impractical for many applications.
Accordingly, it is an important object of the present invention to provide an electrical connector housing in which electrical contacts are removably retained in a manner which resists inadvertent removal due to rearward forces applied to retained contacts, Another object of the present invention is to provide an electrical connector housing in whieh electrical contacts with bulging crimp terminations do not interfere with operation of latching means carried by the housing, A further object of the present invention is to provide an electrical conneetor housing which can be molded in a straightforward single action injection molding process and without reliance upon side coring.
The electrical connector housing of the present invention ineludes a dielectric body having a passageway for removably retaining an eleetrieal contaet. The passageway has a forward stop at its mating end, a flexible latching means extending into the passageway and at least one abutment shoulder on the bottom wall of the passageway spaced from the forward stop a distance generally equal to the length of the contact engagement seetion, The abutment shoulder is spaced from one side wall of the passageway a distance less than the r 2 ~1~6~
width of the contact engagement section and greater than the width of the contact termination section.
The orward stop prevents ~orward movement of the contact within the passageway while the abutment shoulders limit rearward movement. The latching means both engages the contact engagement section to resist rearward forces applied to the contact and exerts a downward force on the contact. The contact is thus held in place against the bottom wall of the passageway and in engagement with the abutment shoulders by the biasing force of the latching means, thereby significantly improving the ability of the electrical connector to resist rearward forces applied to the contact.
In one important embodiment of the invention, the flexible latching means includes two arms in spaced relationship for engaging the contact while straddling the bulging crimp termination of the contact termination section.
The present invention thus solves contact retention problems neither recognized nor addressed by prior art connector housing by providing stationary abutment shoulders which co-operate with flexible latching means to resist rearward forcesapplied to the contacts.
The invention is particularly directed toward an electrical connector housing for retaining an electrical contact having a forward engagement section, a rearward termination section and contact shoulders disposed between the engagement and termination sections. The housing comprises a dielectric - body having a passageway for receiving a contact, the passageway being defined by a bottom wall, a top wall and two side walls, and a forward stop positioned at the mating end of the passageway to limit forward movement of a cGntact inserted therein. An abutment shoulder is located within the passageway positioned on the bottom wall at a distance to the rear of the forward ~2;6;;~6(~
stop generally e(lual to the length Or the contact engagement section and at a distance ~rom one side wall generally less than the width of the cont~ct engageJnellt section and greater than the width of the contact termination sec~ion. The abutment shoulder limits rcarward movement of the contact. Flexible latching means are deflected by the contact engagement section during insertion of the contact into the passageway, for engaging the contact without interference from the contact termination section. The latching means bias the engagement section against the bottom wall within the space defined by the forward stop and the abutment shoulder. The latching means further cooperate with the abutment shoulder and the forward stop to retain the contact within the passageway.
The invention is also directed toward an improved `' electrical connector housing for retaining an electrical contact having a forward engagement section, a rearward termination section and contact shoulders disposed between the engagement and termination sections. The housing has a dielectric body with a passageway for receiving a contact, the passageway being defined by a bottom wall, a top wall and two side walls, the passageway further having a forward stop positioned at its mating end to limit forward movement of a contact inserted therein and flexible latching means for retaining the contact in the passage-way. The improvement comprises abutment shoulders within the passageway positioned at the intersection of either bottom wall with a side wall at a distance to the rear of the forward stop generally equal to the length of the contact engagement section, the abutment shoulders being separated by a distance generally less than the width of the contact termination section. The abutment shoulders cooperate with the latching means to retain the contact within the passageway.
The features of this invention which are believed to -3a-be novel are set forth with particularity in the appcnded ClaiMs.
The invention, together with its objects and the adv.lntages thereof, m.ly be bcst understood by reference to the following description taken in conjunction with the accompanying drawings, - in which like reference numerals identify like elements in the several figures and in which:

The features of this invention which are believed to -3a-be novel are set forth with particularity in the appcnded ClaiMs.
The invention, together with its objects and the adv.lntages thereof, m.ly be bcst understood by reference to the following description taken in conjunction with the accompanying drawings, - in which like reference numerals identify like elements in the several figures and in which:

FIGURE 3a is a plan section view taken along line 3a-3a of FIG. 3 in which the latching means have been removed to improve clarity;
FIGURES 4, 5 and G are section views of Fig. 1 showing the sequence of insertion of an electrical contact into the connector housing.
Turning now to FIGURE 1, the electrical connector housing 10 is illustrated. Housing 10 is molded of resilient dielectric material such as nylon and has a passageway 12 of ; substantially rectangular dimension. Housing 10 may be manu-factured by conventional molding techniques such as single-action injection molding.
A female electrical contact 14 is poised for in-sertion within housing 10. Electrical contact 14 comprises a forward engagement section 16 which narrows to a rearward termination section 20, Contact shoulders 18 are disposed generally between the engagement and termination sections.
Engagement section 16 has a base 22~ and spring rolls 24 curving inwardly to the base and disposed on either side o~
engagement section 16. The spring rolls have rear edges 26, Termination section 20 is preferably secured to an electri-cally conductive insulated wire 28 by conventional crimping techniques.
Passageway 12 of housing 10 has a stop means 30 adjacent its mating end 32. Stop means 30 comprises forward stop members 34 integral with the sidewalls 36 and top wall '' 38 of the housing. The stop means extend downwardly from top wall 38 in substantially parallel alignment to a medial point along sidewalls 36, thereby defining an opening 40 between the bottom edges 42 of the forward stop members 34 and bottom wall 44. Opening 40 accommodates insertion of a complimentary electrical contact into the connector housing to engage the electrical contact supported within the housing passageway, Stop members 34 of stop means 30 are beveled at their bottom edges and spaced from bottom wall 44 to accommodate insertion of the complimentary contact.
Disposed rearwardly from the mating face of housing 10 along passageway 12 are abutment shoulders 46 with beveled faces 48. The abutment shoulders are located at the inter-section or juncture of sidewalls 36 and a bottom wall 44 and extend from the rear of the passageway to end in beveled faces 48 spaced from mating end 32 of the passageway. The abutment shoulders 46 are substantially parallel to each other and separated by a distance slightly smaller than the width of engagement section 16 of contact 14.
Turning now to FIGURES 2, 4 and 6, there is illus-trated a flexible bifurcated latching means 50 terminating in two arms 52 extending obliquely into passageway 12 and directed generally toward mating end 32 and bottom wall 44 of housing 10. Latching means 50 is formed integrally with housing 10 and is upwardly deflectable. Arms 52 are spaced from each other a distance sufficient to define a clearance opening 58 wide enough to straddle contact termination section 20 thereby preventing interference between the latching means and the contact termination section. In its free-standing position, the forward tips 54 of arms 52 are spaced from passageway bottom wall 44 a distance less than the height of contact spring rolls 24 of the contact thereby resisting inadvertent ~lZ6~
rearward removal of the contact, as well as biasing the contact against bottom wall 44.
The latching means 50 is formed integrally with the housing 10 and, because of its configuration and dimension, is resilient and laterally deflectable.
Housing 10 is designed to be molded in a single-action injection molding procedure. In this procedure, a pin enters the mold from the front, as seen in FIGURE 3, clearing stop members 34, and cooperating with another pin entering from the rear of the mold cavity to form both the latching means and the abutment shoulders. Side coring is thus not required which means that the maximum number of cavities can be obtained per mold and the maximum number of housings pro-duced per molding cycle, Electrical contact 14 may be inserted into passageway 12 and retained in alignment with housing opening 40 by the combined action of stop means 30, latching means 50 and abut-ment shoulders 46, This may be accomplished by inserting the electrical contact into the passageway, so that it initially contacts the rearward face 56 of flexible latching means 50 (FIGURE 4) and then deflects the latching means out of the way (FIGURE 5) as it proceeds into the passageway, When the leading edge of the electrical contact meets stop means 30 (FIGURE 6), contact shoulders 18 clear and fall into place behind beveled faces 48 of abutment shoulders 46 (FIGURE 3a) and the contact snaps into the desired position under the urging of latching means 50.
Since the removal forces to which the contact is likely to be sub~ected will be primarily longitudinally directed, abutment shoulders 46 cooperate with flexible latching means 50 to withstand inadvertent removal of the - contact from the housing, If removal of the contact is ~ -6-6~
desired, however, this may be accomp~ished by inserting a conventional flat bladed tool (not shown) through the rear entrance of the passageway to upwardly deflect the latching means thereby permitting contact shoulders 18 to be raised out of the way of the abutment shoulders 46 and the contact to be withdrawn from the passageway While a particular embodiment of the invention has been shown and described, it will be obvious to those skilled in the art that changes and modifications may be made therein without departing from the invention in its broader aspects, and therefore, the objects in the appended claims are to cover all such changes and modifications which fall within the true spirit and scope of the invention.
